To all whom it may concern.-

Be it known that I Gaonon F. Rose, a citizen of the United states, residing at the city of New York, borough of Manhattan, county and State of New Yqrk, have mvented a certain new and usefulFrame Con struction for Type-Writers, of which the following is a specification.

This invention is a frame construction for typewriters, the same being intended for use, more particularly, in connection with machines of the so-called front strike portable variety, although it is apparent that the invention, or parts thereof, may be used, and to good advantage, in connection with other varieties of machines.

The object in view is to secure precision and accuracy in the assemblage of the sev eral'mechanisms, to expedite the work of asseinlilag e,.to -save time and labor in the performanceof the necessary work, and to obtain lightness of weight the whole tending to ultimately effect economy of manu- Generally speaking, it has been and is now the custom to employ cast metal frame constructions, and to resort to separate lirac'kets or equivalent mechanical devices, which require care, skill, time and labor to effect the assemblage with precision and ac curacy. These are obviated by 'my invention to such an extent that the time of the workman in assembling the parts with pre cision ahd accuracy 1s materially econoniized.

One feature of my invention is a frame 'for su porting -or carr ing the working 4 the machine 'sai frame being separate from an outsi e or main frame and positioned interiorly thereof, whereby all the parts may bep'ositioned on the first named frame and the latterjmay be handled or manipu'lated at thewill of the workman priorto the assemblage of the inside frame ornamentalcharacter. v A salient featurejof the interior, frame is and the working parts withinthe exterior frame, the latter being of a finished or a sheet metal construction so bent and ribbed as; tov great stiffness and strength to prevent buckl ng, or distortion thereof and of wawam integral so that the all worfiin 'sde v'i ces such astherilibonmecha' jhrackets etc., mayj beas'sembled wit accu racy, precision and the least amount of labor .on the part of the workman.

- Other features of the invention are a stamped metal front plate forming an element of the interior frame and attachable therewith to the exterior frame, and a sector plate attachable to said interior frame,

' said front plate and the sector plate eachconsisting' of a sngle stamping which is stayed and bracec. to impart the required stiffness and rigid .ty thereto.

Other features ind advantages of the invention will be ap aarent from the following detailed descriphc n.

wardly of the plate and on the lines indieated at d, whereby the rearwardly extending tongues D are adapted to formbraekets for supporting certain parts of the automatic -ribbon reverse mechanism entering into the construction of the typewriting machine.

The top edge of plate A is curved at (1 whereas the bottom" edge extends in a straight line as at a, except at the end portions of the plate, at which end portions the bottom edge is curved or inclined, as at a. The top edge a of plate A is curved to produce fillets at a, and intermediate these apparent that the arms [*I aml D arelfoldable with said wings I5 (3. whereas the other arms I at the upper corners of the plate remain in the [I lane of the plate. Now when the armsmke folded with the wings they fil-letstheplatefiis-piovided wit h. an asm*1$ftehd at a 1- ght angle to the arms I. but

E and a longer arm F, the latter being provided at its free end with an extension G. The arm E is bent at a right angle to the plane of the plate A so as to extend rearwardly thereof and form a bracket for sup porting a reversing lever of the ribbon meci1anism,'the latter forming one of, the working parts of the machine. Said arm F is foldable on the dotted line f and in a direction to extend rearwardly of plate A, after which the arm is bent to produce an inwardly extending lug G which serves as a guide for a rod of the ribbon reverse mechanism, said arm F constituting a support for the spring'barrel by which movement is imparted t0 the platen carriage of the typewriting machine. 4

The stamping is provided with cut-outs 12. near the lower edge and with inwardly extending slots 1: near theupper edge. The wings B C are formedwith inwardly extending arms H positioned below the cutouts b, said arms H being foldable on the line h The upper corners of plate A are provided with extensions I, the lower edges of which are'bounded by one wall of the slots 2', and these extensions are foldable on the lines 11. The plate is provided at its top edge above the fillets if with further extensions J, having the peculiar shape shown more particularly in.l"ig. l, and intermediate the extensions l .l are the notched lugs L. Said notched lu s L are .foldable on the dotted lines Z so that when the top edge a of the plate is'foldcd on the line b so as to form the flange. the lugs li'will extend rearwardly from the plate. as shown in Fig. 2. whereby said parts l1 serve as guides for the rods orstems attached to the platen carriage and forming a part of the carriage shifting mechanism. llie fillets or offsets 1r are bentrearwardly to form brackets for partsvof the, ribbon mechanism.

The extension J' at the right. hand side of the plate is slightly oll'set to hold certain parts of the ribbon vibrator mechanism. The parts of these hie-extensions J below the dotted line. remain in the same plane as plate A.

In addition to tlie'slots heretofore deing in a general curved direction.

by folding said arms ll at a right angle to the'wings B C, said arms II are in the same plane with the arms 1, whereby the arms H I are adapted to serve as means for fastening the interior frame to an exterior frame or casing. In this connection it is noted that the free ends of the arms are bent on the dotted lines h i so as to form flanges adapted for the passage of screws,

whereby the interior frame member may be secured firmly in position to the exterior frame or casin The wings (l are provided at their forward edges with lugs foldable on the line b so that the lugs are positioned for attachment to the front plate, to be presently described, and, furthermore, each win is provided with an additional lug 7) foldable into a horizontal position so as to be available for the attachment of a certain part of the ribbon reverse mechanism.

From the foregoing description it will be seen that the single blank or stamping is cut in such a form as to constitute the entire inner fraine, said stamping or blank being provided with flanges for stiffening or imparting rigidity to the frame, with means for the attachment of said interior frame. to an outer frame or casing, and with a number of logs, brackets, or flanges for mounting certain parts of. the various mechanisms which enterinto the construc tion of the machine, thus reducing the labor of the workman in assembling the working parts in positions requiring precision and"accura( -.y. 'lhe-production of the entire. blank isaurcomphshed by the operation of a single die. aml subsequent to the stamping of said blank it is bent at definite lines and in various directions so as to result in a complete inner frame.

.'\ssocia ted with the inner frame. is a front plate l, shown more particularly in Figs. 3 and l. and assembled with-the one-piece inner frame in an operative position within an outer frame or casing. as shown in Figs. 7 and 8. This front plate. is provided with a series of steps I and with a likeseries of notches 1) in its top edge, the latter extend- Furfront thermore, the front plate is foldable on the dotted line 1 so as to produce'an offset 1), shown in dotted lines in Fig. 4, and said lower edge of the front plate is formed with a series of notches p, three of which are indicated in full lines and the remaining notches are indicated dia rammatically bythe single lines. At its en s the front plate is provided with extensions p adapted to be folded at right angles to the late so as to form. lugs which are adapte for engage ment with the inner surfaces of the outer frame or casi This front plate is cut or stamped in ifie required form by one operation of a suitable die, and subsequent to the roduction of the plate its extensions p .are ent to form the lugs through which are adapted to pass screws for -attaching said front plate to the exterior frame. The front plate extends across. the open space between the wings B C of the interior frame, and the lugs b on the wings of said interior frame engage with one face of the late and are fastened thereto in an suitab e way, as for example by screws. t is apparent that the stepped edges 11 and the notches 1) thereof will position with precision and accuracy the brackets for the angle levers employed betweenthe type bars and ey levers, whereas the notches p in the lower edge of the front late serve as guides for the key-levers of tie typewriting machine.

In Figs. 5 and 6 there is shown a sector plate Q to which is adapted toybe attached the brackets on which the key levers are hung, said sector plate being positioned in rear of the front plate. The sector plate is cut, or stem ed from a single piece of sheet metal and tile operation of cutting and perforating this plate will distort or buckle it notwithstanding extreme care in the stamping operation. To overcome this tendency of the metal plate to buckle, I bend it along the lines q so as to produce flanges q", the o eration of bending which flanges effectua ly straightens the late so that it remains in a. true and straig it condition. The sector is'prot'ided at its end with attaching flanges 1 and at its bottom edge with a lug q", the latter bein bendable at right angles to the'plane o the plate, whereas the flanges q lie in the plane of the plate, although the flanges may be bent up to impart stiffness thereto. R designates an exterior frame which is struck up from a single piece of sheet metal so as to form the back,.s1des and front, said I sides having. the-form shown more particu larly in Fig. 8. T-hejfr-ame is provided on its edges with the inwardly extending flanges T, but at the frontof the frame the top edges thereof are curled'over at r in order to impart the desired finish to said fra men panels operating in impart the desired stiifness and rigidity to the outer frame.

It will be seen that the interior frame,

the front plate and the sector plate are produced rapidl and economically by simply stamping tn: parts from sheet 'metal of the required gage and strength, after which the interior frame, the front plate and the sector plite are adapted to be assembled and fastened in the required accurate position without undue care on the plant of the workmun. 'The exterior frame is of the usual ornamental character and if it is handled from the beginning to the end of the operation of assembling the working parts, tlefinish ofthis frame is marred and soiled by the hands of the workman. According to my invention, however, all the operating parts are assembled on the'interior frame, after which said interior frame with the working parts and the plates P and Q are brought together and fastened within the exterior frame, thus saving the operations of handling the exterior frame, exce pt upon the final assemblage of the macline. It'is apparent that the exterior frame is composed of sheet metal cut or stam ped in the required form and bendable so as to produce the sides. front and rear, t1 1e required stiffness and rigidity in the exterior-frame being obtamed by the pro ision of thefian'ges-r r Having thus fully described the .invention, what I claim .as new, and desire to. secure by Letters Patent is:
